[0008] The outer end of the hardware connecting shaft is connected to the side of the connecting structure via a bearing;

[0009] The fan blade hangs naturally downwards around the metal connecting shaft under the action of gravity. When the drive motor starts, the fan blade unfolds horizontally around the metal connecting shaft under the action of centrifugal force.

[0010] A further preferred embodiment is that the connecting structure includes a connecting block, a transverse mounting channel formed on the connecting block, and a limiting protrusion integrally formed on the side of the connecting block;

[0011] The connecting block is provided with a circular hole that communicates with the horizontal installation channel;

[0012] The outer end of the hardware connecting shaft is provided with a screw hole. The bearing is set in the transverse installation channel and fixed by at least two screws. The long stud passes through the bearing and the round hole and is threadedly fixed to the screw hole of the hardware connecting shaft. The limiting protrusion is on the same side of the connecting block as the hardware connecting shaft, and the limiting protrusion is located between the hardware connecting shaft and the fan disc.

[0013] When the fan blade body is horizontally unfolded with the hardware connecting shaft as the center, the bottom surface of the end of the fan blade body abuts against the upper limit of the limiting protrusion.

[0014] A further preferred embodiment is that the fan blade is inclined, with the side of the fan blade closer to the support rod being higher and the side farther from the support rod being lower.

[0015] A further preferred embodiment is that the length of the support rod is greater than the distance from the end of the fan blade to the edge of the fan disc.

[0016] A further preferred embodiment is that the tilt angle of the fan blade is 10-20°.

[0017] A further preferred embodiment is that the fan blade is a plastic structural component.

[0018] A further preferred embodiment is that the top of the fan structure is fixed with a hanging rod or a ceiling mount.

[0019] This utility model has the following positive effects: The structure of this utility model is reasonable. Its fan blade is connected to the support rod through bearings and hardware connecting shaft. Therefore, when the drive motor is not started, the fan blade will rotate in a vertical state around the hardware connecting shaft under its own weight, which helps to reduce the overall volume and facilitates packaging and transportation. When the drive motor is started, the fan blade will unfold into a horizontal state under the action of centrifugal force, ensuring the effectiveness of blowing. It is stable and reliable in use and has strong applicability.

[0020] Furthermore, there is a limit protrusion on the side of the connecting block. When the fan blade unfolds under the action of centrifugal force, it will abut against the top surface of the limit protrusion to limit it, ensuring the effectiveness of horizontal unfolding.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] See Figures 1 to 5 As shown, a fan light with retractable blades includes a fan structure 1 and a lamp structure 2 disposed below the fan structure. In this embodiment, the lamp structure is a conventional structure of the prior art, so it is not described in detail, but simply applied. The fan structure includes a drive motor, a fan disk 3 connected to the drive motor, and a plurality of fan blade structures 4 connected to the fan disk. The fan disk is a conventional structure of the prior art and rotates together with the drive motor when the drive motor starts.

[0033] In this embodiment, the fan blade structure includes a support rod 41, a fan blade body 42, and a connecting structure 43; wherein the fan blade body is a plastic structural component. The support rod is a metal structural component, and the length of the support rod is greater than the distance from the end of the fan blade body to the edge of the fan disk. This ensures the effectiveness of the fan blade body's downward rotation.

[0034] During assembly, one end of the support rod is fixed to the side of the fan disc by a screw, and the other end of the support rod has an installation cavity 5. The connecting structure is set in the installation cavity and locked and positioned by studs. One end of the fan blade has a circular mounting hole 7. A metal connecting shaft 6 is injection molded and fixed in the circular mounting hole. The outer end of the metal connecting shaft has a screw hole 12. The bearing is set in the transverse installation channel and fixed by at least two screws 8. In this embodiment, the stability and reliability of the installation can be guaranteed. In use, the fan blade hangs naturally under the action of gravity with the metal connecting shaft as the center. When the drive motor starts, the fan blade unfolds horizontally with the metal connecting shaft as the center under the action of centrifugal force.

[0035] In this embodiment, the connecting structure 43 includes a connecting block 431, a transverse mounting channel 432 formed on the connecting block, and a limiting protrusion 433 integrally formed on the side of the connecting block. The connecting block is provided with a circular hole that communicates with the transverse mounting channel.

[0036] The outer end of the metal connecting shaft is provided with a threaded hole. The bearing is set in the transverse mounting channel and fixed by at least two screws. The long stud 11 passes through the bearing and the round hole and is threadedly fixed to the threaded hole of the metal connecting shaft. The limiting protrusion is on the same side of the connecting block as the metal connecting shaft, and the limiting protrusion is located between the metal connecting shaft and the fan disc. In actual application, the end of the metal connecting shaft can also be directly fixed in the inner ring of the bearing, and then the bearing is snapped into the transverse mounting channel and positioned by pressing against the outer ring of the bearing with screws. Figure 5 As shown.

[0037] When the fan blade is horizontally unfolded around the hardware connecting shaft, the bottom surface of the end of the fan blade abuts against the upper limit of the limiting protrusion. The height of the limiting protrusion can be set as needed, and it is mainly used to support and limit the fan blade when it is unfolded to prevent it from rotating excessively.

[0038] Furthermore, the fan blades are inclined, with the side closer to the support rod higher and the side farther from the support rod lower. The inclination angle of the fan blades is 10-20°. This ensures the effectiveness and reliability of the airflow.

[0039] In this embodiment, the top of the fan structure is fixed with a ceiling mount 9. It can be fixed to the ceiling, ensuring the stability and reliability of the installation.

[0040] This utility model has the following positive effects: The structure of this utility model is reasonable. Its fan blade is connected to the support rod through bearings and hardware connecting shaft. Therefore, when the drive motor is not started, the fan blade will rotate in a vertical state around the hardware connecting shaft under its own weight, which helps to reduce the overall volume and facilitates packaging and transportation. When the drive motor is started, the fan blade will unfold into a horizontal state under the action of centrifugal force, ensuring the effectiveness of blowing. It is stable and reliable in use and has strong applicability.

[0041] Furthermore, there is a limit protrusion on the side of the connecting block. When the fan blade unfolds under the action of centrifugal force, it will abut against the top surface of the limit protrusion to limit it, ensuring the effectiveness of horizontal unfolding.

[0042] Example 2

[0043] See Figures 6 to 7 As shown, this embodiment is basically the same as embodiment 1, except that: in this embodiment, a hanging rod 10 is fixed to the top of the fan structure. It can be suspended from the ceiling to ensure the effectiveness of assembly and use.

[0044] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
